Helping Dogs Feel Calm & Confident

Aggressive Dog Training in Connecticut

One of the most difficult, necessary, and rewarding behaviors to correct in a dog is anxiety and aggression. These behaviors can be learned, genetic, or innate. When a dog feels threatened, their natural response is either fight or flight.

Most dogs will try to distance themselves from the perceived threat; if that's not possible, they may resort to aggression or submission. Some dogs, particularly those who see themselves as confident pack leaders, may turn to aggression as their first response.

Both of these reactions are rooted in anxiety and can be effectively addressed with Dog Training Elite's balanced aggressive dog training in Connecticut.

Understanding Aggressive Behaviors in Dogs


Read More
Read Less

Aggression is one of the most concerning behaviors your dog can exhibit. If left unchecked, an aggressive dog can pose a serious threat to family members, strangers, other dogs, or even themselves.

Many dog owners struggle with how to recognize early warning signs of aggression or how to effectively address these tendencies. Identifying and managing aggressive behavior early on is crucial in preventing it from escalating into more dangerous situations.

Common signs of aggression in dogs include:

  • Growling or bearing teeth
  • Threatening barks
  • Standing rigid and/or taller
  • Raised fur
  • Nipping and biting

Aggression often stems from underlying issues like fear, anxiety, improper training, or negative environments. Dogs that have been rescued from poor situations or found on the street are particularly susceptible to developing aggressive behaviors.

At Dog Training Elite, we specialize in professional dog training for aggression, helping your dog transform from fearful or aggressive to a happy, friendly, and loyal companion.

    Dog Training Elite of Southern CT was excellent! After thorough research near Westport, CT, we picked DTE and we are very happy with our decision. All of our expectations were exceeded. Howie was is now fully trained as a Service Dog. All sessions were on-time with follow-up notes texted to me. Howie really enjoyed the sessions too! It was a smooth process for all.

    We took in our four year old English mastiff Hank as a foster to adopt in January 2026. He came to us with zero history but it was immediately apparent he had some serious reactivity and behavioral issues. At 165 pounds, it was a very big concern. We looked into board and train but knew that would not be the appropriate solution for Hank. We tried another local training facility and found them to be a waste of time and money. Our neighbor recommended Jason, having recently trained with him for her service dog. In our first meeting with Jason, we knew he would be the right fit for us. He was undaunted by Hank’s size and reactivity. He made sure to understand our goals and the approaches we felt comfortable in trying with Hank. He never pushed us into only one method and continually checks in to see if we want to change our goals or approaches. He has been available to us when we had issues arise between training sessions. His calm, clear instruction is so appreciated. He has trained us in how to manage our new guy. His understanding of dog behavior and openness to solutions that fit the dog and family is invaluable.

    We had an excellent experience with Jason and Iliana. Our 2 year old GSP is an amazing dog but full of energy and curiosity - we love taking him on hikes and wanted to strengthen his off leash recall, as well as leash pulling. We tried other training approaches but he seemed immune! DTE helped us strengthen our communication and trust with our pup, and his overall obedience. They come to your home, meet you out in public training locations, and offer 1:1 and group sessions. Thank you team!

    We absolutely loved our training with Jason and Dog Training Elite. He was so knowledgeable and helpful working with Walnut. We have seen so much improvement in Walnut's anxiety, behavior in social settings, and in listening to our commands. We have been able to enjoy walks with him when he can meet new pup friends in our neighborhood, and we are even able to relax when we take Walnut to the brewery! Can't wait to attend our group classes to see his continued improvement.

    Illiana has been awesome for our dog, Lenox. She is an excellent trainer and she teaches in a way that makes it easy for me to implement everything we practice in our sessions, in every day life when she is not here.

    Jason came for the initial visit. We were impressed with his presentation and signed up. Illiana is our trainer who comes to the house and we really like her because she has a special way about her. Pia and Shultz get all excited when she comes. Both pups are responding nice to the training methods introduced at home and at the group classes. We are very happy with the service. Thank you. Ed an Cat- Pia an Shultz

    We had such a great experience with Dog Training Elite while working with our 8-month-old Golden Retriever puppy! Jason did our initial evaluation at our home and was incredibly thorough, attentive, and thoughtful. He took the time to understand exactly what we wanted to work on and created a training plan that was truly tailored to our puppy and our goals. We really appreciated that the approach was effective without ever feeling aggressive or overwhelming for our puppy. We then continued our 1:1 training with Iliana, and we saw tangible improvements from day one! She was patient, knowledgeable, and so great at helping both us and our puppy understand what we were working toward. The entire team has been flexible, friendly, and responsive, and it’s very clear how much they genuinely love and care about dogs. We’ve been so happy with the progress we’ve made and are looking forward to continuing our training with the group classes. Highly recommend Dog Training Elite!

    From day 1 Eliana from Dog Training Elite was professional and taught us many things to work with Hazel. Hazel just 11 months and has a personality befitting a Shih Tzu so it was challenging but with patience eventually she caught on. We highly recommend DTE and look forward to Hazel’s group lessons.

    We’ve had a great experience with Dog Training Elite of Southern CT so far! The personalized training they provide for Hope has made a noticeable difference with leash walking, basic obedience, confidence, and socialization. We really appreciate that the training is tailored specifically to her rather than feeling like a one-size-fits-all approach. We’ve already seen a clear improvement in Hope and are very happy with the progress she’s making. We would definitely recommend Dog Training Elite of Southern CT to anyone looking for professional, personalized dog training!

    Jason has been an awesome trainer for Berkeley. We started training when she was just 12 weeks old, and she turned one at the end of April. In less than a year, my pit mix has become a reliable psychiatric service dog that I confidently take everywhere with me. Berkeley has flown with me on four cross-country flights between Connecticut and California, comes with me to all public places, and handles those environments incredibly well. The foundation Jason helped us build from the very beginning has made all the difference. Berkeley had some anxiety in certain situations early on, and Jason gave me practical advice and tools to help us work through it. His guidance helped build her confidence just as much as her skills! If you’re willing to put in the time and effort with your dog and follow Jason’s advice, you’ll absolutely see the results. I highly recommend him!

    We had a wonderful experience working with Ileana and the team. She was able to walk my fur son through all the steps. Scheduling was extremely easy and group session were a great experience. We made meaningful progress with socializing. I would recommend the team 100%!

    From the time my dog was 8 weeks old until now two years later I have taken my dog to Jason at Dog Training Elite of Southern CT for obedience and service dog training. His skill and expertise has been nothing less than exceptional. He taught me how to understand and work with my dog effectively bringing her to the certified service level she has recently attained. I am so grateful for all that he has done. He allowed me to gain confidence within myself throughout the training process. Training me to train her. Thank you Jason for all you have done I will always recommend you to others. I wouldn’t have made it as far as I have without your guidance and support.

    Had a wonderful experience with Jason and Illana. My dog has taken large strides in controlling herself around people and other dogs. She's a terrier with a spicy attitude! Still have few more group sessions. Can't wait. I now have a basic idea on how to handle her.

    Me and my Catalan sheepdog mix/supermutt girl, Dooley, have been learning so much with Illiana, one of the best trainers ive met in my 27 years of dog-owning. Because Dooley loves to run, we've been focused on e-collar training so that I can take her off-leash to various areas and keep her safe and under my command. You think you know dogs and then you meet a trainer like Illiana and realize there's a lot more to learn! I definitely recommend Dog Elite and their trainers.

    DTE has proven to be the right choice for our GSD. Jason has put us on the right path for this training to be successful. Coraggio responds well to Jason. We actually feel like proud parents. This was money well spent. Stratford ,CT

    We absolutely LOVE Dog Training Elite. Jason has been so great with our dog Rhodes. He was a very difficult puppy but with patience, persistence and guidance - he is now a well mannered member of society (most of the time haha). Group training has also been a great help. It’s exposed Rhodes to other dogs, people and environments which have helped widen his training scope. Couldn’t recommend them more - with every penny!

    Jason primarily helped us with leash manners for our newly adopted rescue pup. We’ve seen so much improvement so quickly and it has helped make walks more enjoyable for us all. He’s very generous with his time and happy to answer any and all questions as things come up. Highly recommend Jason!

    DTE has helped us so much since starting with them. We have two dogs that were working through a lot of reactivity and separation anxiety and the change we have seen in them this early on is so amazing. Jason has give us the training expertise and tools to continue to build on the foundation we have created, and that’s just in a handful of one on one training sessions. They come to you and work in your environment which is extremely helpful. Additionally, having group classes where our pups can continue their learning and be exposed to other dogs as well is a huge plus. I’m so happy we came across DTE. Their philosophy and the way they treat our pups is very thoughtful and done with lots of care. Couldn’t recommend more!

Our Personalized Aggressive Dog Behavior Training

At Dog Training Elite, we understand that every dog is unique, and we have developed a comprehensive training program specifically to eliminate aggressive behaviors across various breeds.

  1. Initial In-Home Assessment: We begin with a free in-home assessment where we meet your dog to understand the underlying causes of their aggression, anxiety, or fears. During this session, we identify triggers and gather the necessary information to develop a personalized training plan.
  2. Personalized Training Plan Development: Based on the assessment, we create a customized training program tailored to your dog’s specific needs. This plan targets the unique behaviors and triggers that contribute to their aggression.
  3. Building Confidence and Establishing Leadership: Our trainers work closely with you to establish your role as the pack leader in your home. For fearful and anxious dogs, we focus on building confidence and reducing the fears that trigger aggressive behavior.
  4. Desensitization and Obedience Training: For overly aggressive dogs, we use desensitization techniques to reduce reactivity to triggers and anxieties. Obedience training are key components of this stage.
  5. Group Class Integration: Once your dog reaches a safe baseline of obedience, we gradually introduce them to group class settings. These classes are designed to help your dog reintegrate into social environments successfully. For safety, a muzzle is required during these sessions to protect all dogs involved.
  6. Ongoing Support and Reinforcement: We continue to support you and your dog throughout the training process, offering guidance and reinforcement to ensure lasting success. Our goal is to help your dog become a loving, loyal, and well-behaved member of your family.
